You should be ok to just have an extra rain jacket in your back pocket (which is quite sensible for any ride, anywhere). For this purpose the Race Cape is great.
If it's warm in the valley and you feel you're slightly over-dressed for the climb then undo your zip and let your jacket/jersey flap about.
Don't dress like an eskimo based on the fact you're going to possibly get very cold at the top. Because you probably won't.
It's pretty shit descending in the cold and the rain, but having extra clothes only makes it slightly less shit.
